Patent No. of Plastic Extruder Die Head: ZL0161440.8 is PVC hollow inner screw foaming tube mould and has gained national practical new patent. Since entering into the market, they have gained good praise from the clients and are exported to Iran, Russia and Egypt.
This production line adopts three layers combined extruding technique and advanced prescription as well as the co-extruding machine head with spiral chute and rotational mandril with constant speed, it can produce PVC core layer foaming tube and PVC inner screw sound deadening drainage. This kind of tube has light weight—about 0.92-1.09/CM3 (the non-foaming PVC tube is 1.4g/CM3); good sound insulation effect—the water will fall along with the tube helically, therefore the noise of the water problem has been solved. Moreover, it is proved by experts that the noise of the PVC inner screw foaming tube is 5-7 db lower than core layer foaming tube, 7-15 db lower than the solid wall PVC hard tube, the noise of the hollow wall inner screw sound deadening drainage is 20-30 db lower than the solid wall PVC tube.
